The contents were listed as "alloy rings," the CBP said in a statement.

The agency said its officers "noted the poor craftsmanship and detained the rings to verify authenticity with the National Football League, the trademark holder."

The NFL confirmed the rings were fakes, and the federal agency seized them on June 29.

"The rings represented many Super Bowl champions, including the Eagles," the CBP noted.

The Eagles last month unveiled a World Championship Fan Ring, offering 127 rings for $11,127 each.

That ring has since sold out. It was made of 10-karat white gold and featured 219 diamonds and 17 green sapphires, according to the team.

The "127" ring took its name from the combined jersey numbers of three players who executed the Philly Special in Super Bowl LII, described by the Eagles as "one of the most iconic moments in franchise history."
